In coating paper-making fibres, such as cellulose, wood, jute, hemp, sisal, manilla, wool, rayon, nylon, leather, asbestos and glass fibres, with a water-insoluble substance, an aqueous dispersion of the fibres and a polyvinyl ether, having the formula (R-O-R<SP>1</SP>) n  wherein R is vinyl and R<SP>1</SP> a lower alkyl radical, whose solubility in water decreases with increasing temperature, which dispersion may contain acetic acid or alum, is heated to precipitate the polyvinyl ether on the fibres, and an aqueous dispersion of the water-insoluble substance is then added. The aqueous dispersion may be cooled to a temperature below the precipitation temperature of the polyvinyl ether before the water-insoluble substance is added and, after the addition, may be reheated. Polyvinyl methyl ether which is soluble in water at 20‹ C. and is precipitated therefrom at a temperature above 30‹ C., e.g. 35‹ C., is a suitable polyvinyl ether. Suitable water-insoluble substances are: natural rubber, polyvinyl chloride, polyvinylidene chloride, copolymers of vinyl chloride and vinylidene chloride, polyvinyl acetate, copolymers of vinyl acetate and vinyl chloride, polyacrylates, polymethacrylates, polyisoprene, polychloroprene, copolymers of butadiene and styrene or acrylonitrile, polystyrene, linseed oil, rosin, alkyd resins, ester gum, paraffin wax, petroleum jelly, carnauba wax, microcrystalline wax, asphalt, tar, pitch, bitumen and terpene resins, phenol - formaldehyde, urea - formaldehyde, melamine-formaldehyde and polyester resins. The dispersion of the water-insoluble substance may contain a non-ionic soap such as a fatty alcohol-ethylene oxide condensate or an anionic soap such as the sodium salt of an alkylated naphthalene sulphonic acid. The coated fibres may be made into paper, artificial leather (Example 2) or paper-board.

Title: Improvements in steam reducing valves
IPC: F01B25/00
Filed: 1921-01-24
Abstract: 179,243. Wingfield, B. R., and Steam Fittings Co., Ltd. Jan. 24, 1921. Valves controlled by pilot or relay valves. - A steam pressure - reducing valve is controlled by the temperature of the steam at reduced pressure by means of a thermo stat, operated by the expansion of a liquid, acting on the reducing - v a l v e through the medium of a pilot valve. The thermostat comprises a tube 1 filled with liquid and containing a spirally-corrugated metal tube G, the lower end of which is fixed to the base H, and the upper end to a cap K carrying a rod F terminating in a valve D. A similar corrugated tube N is arranged in the upper part of the tube 1, and its rod P carries a nut Z having a pin B<1> projecting into a slot B<2> in a fixed sleeve A. The nut Z is pressed downwards by a spring D" and is prevented from turning relatively to the sleeve A<1>. The latter may be rotated on slackening the nut C<1>, in order to adjust the tube N upwards or downwards to vary the initial setting of the valve D. Steam flowing through the inlet 10 passes through the valve D and pipe X to operate the piston C and thus lift the main valve B to allow the steam to pass to the outlet. The reduced steam passes through the conduit V to the casing R, so that if its pressure and consequently its temperature become too high, the thermostat is actuated and the valve D is partly closed, which results in a corresponding partial closure of the valve B. Any increase in temperature of the thermostat after the valve D is closed produces a further expansion of the liquid which is absorbed by the compression of the spring D<11>. Specifications 25086/13 and 4190/15 are referred to.

Title: Improvements in or relating to absorption refrigeration systems
IPC: F25B15/06
Filed: 1954-02-04
Abstract: 747,881. Refrigerating. CARRIER ENGINEERING CO., Ltd. Feb. 4, 1954 [April 16, 1953], No. 3377/54. Class 29. In continuous cycle absorption refrigerating apparatus of the type described in Specification 639,413 solution from the absorber is preheated prior to its entering the generator by being led in heat exchange with refrigerant in the condenser. Solution is withdrawn from the absorber 3 through a pipe 18 by a pump 17 which supplies it through pipes 19, 20 to a coil 7 located in a pan in the upper part of a shell 5. The pan serves as the condenser and the lower part of the shell acts as a generator and contains heating pipes 6. From the coil 7 solution passes to the generator space through a pipe 21. The level of solution in the generator is maintained constant by a float valve 45 and excess solution flows by pipe 10 into a second shell 8 maintained at a lower pressure than is shell 5. The solution is thus flashed in shell 8 and the vapour formed is condensed on a water-cooled coil 12 in the upper part of the shell. Solution returns from the shell 8 to the absorber 3 through a pipe 13. Condensate from the twocondensers passes through pipes 29, 30 and a common pipe 31 to the evaporator 4. The tubes 6 of the generator are supplied by steam through a valve 40 controlled by the temperature of liquid refrigerant, i.e. water, leaving evaporator 4 through pipe 33. In a modification, Fig. 2, (not shown), the second generator-condenser shell 8 is dispensed with and the main condenser in shell 5 is cooled both by the solution passing to the generator and by a cooling-water coil.

Abstract: Provided in a casting mould (30) are a number of shaped parts (32) corresponding to the number of the contact pins and into which the contact pins (6) are pressed in a manner forming a seal either solely by the pressure of the plastic material flowing into the casting mould, or in addition by a press-on means belonging to the casting mould. For this purpose, the shaped parts and the contact pins (6) each have a complementarily configured section (35, 35a) for achieving the sealing effect. The shaped parts are configured in the entry region of the contact pins so as to produce on the finished connector socket (1) a surface configuration which has the effect of increasing the creepage current path. <IMAGE>

Abstract: 287,438. Ellis, G. B., (American Sheet & Tin Plate Co.). Sept. 13, 1926. Recovering fats and oils from waste waters; oils, purifying.-Apparatus for separating and recovering oil such as palm oil, from an emulsion of oil and water, comprises a trough 31 from which the emulsion flows to a treatment tank D in which it is heated, agitated, and broken down by addition of a suitable reagent, means such as a pump 47 for removing the separated oil, screening-means 48, a drier 55, and a centrifuge 62. The emulsion is heated, say to 140‹ F., and agitated in the chamber 33 by means of steam supplied from a pipe 39, and is broken down by addition of say sulphuric acid, supplied from a tank 42 by a pump 43. The broken emulsion overflows a wall 34 into a separating- chamber 34<a>, the oil rising to flow over the inclined top of a wall 35 into a chamber 35<a> heated by a steam coil 41, this action being assisted by a steam coil 38, and the water passing away through a stand pipe 45. Instead of sulphuric acid, other acids, nitrecake, waste pickle liquor, lime, calcium chloride, iron or sodium sulphate, or alum, may be used to break the emulsion, but it is stated that.in some cases the oil will then settle to the bottom and other means of separation will be necessary. Passage through the screen 48 removes any large particles oi foreign matter, and the oil, which still contains about 60 per cent of water, is collected in vat 50 heated by a steam coil 51, and pumped by a pump 53 through a coil 54 located in the steam-heated drying-drum 55, and discharged at a temperature of 300‹ F. into a stack 56. The water content of the oil passes up the stack as steam or vapour, and the dry oil flows by way of steam-heated tanks 59, 60, which maintain its temperature at 300‹ F., to the centrifuge 62 for final purification.
